FLUID=EJECTOR.

SPECIFICATION forming part of Letters Patent No. 346,878, dated August 3, 1886.

Application filed May 7, 1886. Serial No. 201,422. (No model.)

To all whom it may concern:

Be it known that I, CHARLES lVHI'lE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Fluid- E'ectors of which the followin is a s )eciiica-- 7 Z: l

tion, reference being had therein to the accompanying drawing.

My invention relates to improvements in IO fluid-ejectors and valve mechanism therefor, as illustrated in the accompanying drawing, in which the ejector is arranged in awell and shown in sections.

The letter A designates the well arranged I 5 to receive and hold the static water, which accumulates therein in sufficient quantity before the ejector B is put in operation, which continues to operate until the water has nearly all been ejected from the well.

The ejector B consists of an ingress-passage, a, for the static water, communicating with the port I), which is connected to the dischargepipe 0. Directly opposite and central to the port I) is a small ingress opening, 0, through which the pressure-water passes from the pipe D, and as it crosses the passage a it acts on and ejects the static water from the well A by way of the discharge-pipe O.

In ejeetors of this class,by which static water is elevated by a similar fluid under pressure, it is dosh-able that the pressure-water should be applied suddenly to give the static water momentum, and it is also desirable,when the ejector is used in a well that accumulates water slowly, to have it operate at intervals, or when suflicient water has accumulated in the well to eject the same and then remain inactive until again required. Therefore I arrange a valve of special construction, and attach a 0 float thereto in such a manner that the above .requircments are accomplished.

Concentric to the port 0 is formed a chamber, 11, in which is neatly fitted a pistonhead, e, that forms a valve between the pressurepipe D and the port 0. ,Froni the head a projects a stem, 0, that extends to the outside of the chamber by passing through the cup f, with its outer end provided with an elongation-groove, g, in which the short end h of the bell-crank is plaeed,and by which the said end It can move in either direction a certain distance without operating the valve. The cap f is attached by being threaded into the casing, or otherwise, and it is provided with a projection, 2', that forms a bearing for the stem 0. This bearing is vertically slotted to permit the end 71 of the bell-crank to pass to and act on the stem 6. The bell-crank is pivoted to the casing of the ejector at k, with its long end h secured to the float-ball E, by which the valve 6 is moved positively a certain distance by the float and arm K, and through the remainder of its throw is moved quickly or instantaneously by the pressure of the fluid.

To prevent the water that the discharge-pipe contains just after the ejector ceases to act from running back into the well, and in case the pressure-water at different periods is not of a suflicient head to accomplish the ejection of the static water when the well has filled and the valve 0 is opened thereby, I arrange a valve at the inlet of the passage a, to automatically close and open, as may be desired, the same consisting of a casing, F, secured over the opening,in which is placed the disk Z, that is seated downwardly by the weight of any accumulated water in the ejector, and which is lifted and seated against the opening of the passage a when the vacuum is formed by the ejector being put in operation. The static water then passes into the passage a through the holes m, thereby permitting the static water from the well to be ejected, and that contained in the pipes or ejector is prevented from passing back into the well.

In the operation,when the well has filled to a certain height with water, the float E brings the short end h of bell-crank in contact with the outer end of the groove g,which draws the stem and head 0 outward, thereby permitting the water in the pressurepipe D to pass to the ejector, thus putting the same in operation the port 0, thereby quickly seating and unseating the said head, which results in apply- .ing and cutting ofl the pressure-water, as desired,when the well A has filled or emptied.

Having described my invention, what I claim is 1. In combination with an ejector, B, and the pressurepipe D, the piston-head e,plaeed in relation with the two, that forms a cut-off valve which is moved positively a certain distance by the float and arm K, and through the remainder of its throw is moved quickly or instantaneously by the fluid-pressure.

2. The combination of the ejector B," the discharge-pipe O, the pressure-pipe D, and the piston-head 6, arranged to form a cut-off, and be held open or closed by the pressure of the fluid in the pipe D when placed in either position, as specified.

3. The combination of the ejector B, the

pipes O and D; the piston-head e, arranged to CHAS. WHITE.
